چکیده
A study was carried out in the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Old Brahmaputra Flood Plains Soil (AEZ-9) during December 2001 to April 2002 to find out the effect of seed rates and NPK levels on dry matter accumulation and grain yield of foxtail millet (Setaria italica L. Beauv.). Four seed rates viz., 8,10,12, and 14 kg/ha and five levels of NPK fertilizers viz., N0P0K0, N10P8K5, N20P16K10, N30P24K15, and N40P32K20 were included in a split plot design with three replications. Dry matter accumulation pattern was determined by harvesting 10 plants randomly at 30, 60, 80, and 102 DAS (days after swing). The yield and yield contributing characters of foxtail millet were influenced by seed rates and NPK levels except tillers per plant and 1000-grain weight significantly. Generally its production rate was 0.86 t/ha when it was grown in char lands in sandy loam soils, the highest grain yield (1.62 t/ha) was produced by 10 kg seeds/ha, which was identical with 12 kg seeds/ha. In case of NPK levels, the treatment was N30P24K10. In case of interaction, the treatment combination 12 kg seeds/ha and N30P24K15 produced the highest grain yield (1.77 t/ha. In case of interaction, the treatment combination 12 kg seeds/ha and N30P24K15/ha gave the highest grain yield.

Testing the Implications of the Olson Hypothesis
Considerable attention has been paid to the hypothesis, advanced by Olson, that accumulations of interest groups build up over time and retard economic performance. Most previous tests of this hypothesis have been based on comparisons of growth rates. In this paper, it is argued that comparisons of income levels yield a superior test. Strong forms of the Olson hypothesis, in which shocks such a...

Literature review and synthesis of growth rates of aquatic protists focused on the role of temperature in the formation of massive annual algal blooms in high-latitude ecosystems. Maximal growth rates of herbivorous protists equaled or exceeded maximal growth rates of phototrophic protists at temperatures above 15uC. Maximal growth rates of herbivorous protists declined more rapidly with decrea...
